In the field of dynamic simulation of renewable energy systems, the use of generic dynamic models that reproduce the behaviour of renewable electrical machines (WTG, PV, BESS) and their central control system (PPC) is well known. These mathematical models are provided by various entities, of which the generic models developed by the Western Electricity Coordinating Council (WECC) stand out, as their use is very extended. Most of these models are available in the libraries of leading industrial simulation software such as: ? Siemens PTI’s PSS/E ? DIgSILENT PowerFactory ? EMTP-RV ? PSCAD Many Transmission System Operators (TSOs), including ERCOT (Texas), EirGrid (Ireland) and CENACE (Mexico), among others, require the use of these models for the dynamic simulation requested in their Grid Connection Codes. The preference for these standardised models lies in the simplification of the evaluation and understanding of the plant dynamic model, as their functionalities and control loops are widely known. In addition, the use of generic models allows the operator greater simplicity when updating the model to a new version of the simulation software. Some of the most recent and currently generic models for renewable energy plants are the following: ? REPC_A – Power Plant Controller Model. ? REEC_A – REEC_D – Renewable Electrical control model for PV and BESS converter and WTG. ? REGC_A - REGC_B – Generator model for PV and BESS converter and WTG. A thorough understanding of the benefits and limitations of these models is essential to maximise their usefulness in these simulation environments. Ingelectus has extensive experience in the analysis and application of these models on different simulation platforms, enabling us to understand and master their characteristics. This expertise allows us to provide the most appropriate configurations based on the specific requirements of each renewable energy plant. #WECC #genericmodels #dynamicsimulation #renewableplants #gridcodes

A clear demonstration of our work quality. Rather than relying on the software alone, we thoroughly cross-check all design work ensuring our customers get the best and optimized system designs. While working on the rear bifacial gain of PV modules to assess the yield of a solar farm accurately for our client from Brazil, we noticed discrepancies between the results we expected and the simulation results provide by System Advisor Model (SAM). After thorough assessment of SAM's documentation, we finally captured the issue in SAM's calculation and reported that to them. https://lnkd.in/eKp8tnP7 #solar #systemadvisormodel #sam #nrel #solardesign #engineering #pvdesign #energysimulations #financialmodeling #solarfarmdesign

Understanding the Temperature-Corrected Performance Ratio (PR) is crucial in assessing the efficiency of photovoltaic solar power plants. By adjusting for temperature variations that impact the modules' efficiency, accurate analysis is achieved. This correction is vital as module efficiency decreases above the standard temperature conditions. Here's why temperature correction is essential: - Accuracy in Analysis: Calculating PR without considering temperature can result in misleading outcomes, particularly on hot days, leading to inaccurate performance assessments. - Financial Implications: Accurate metrics are imperative for investors to evaluate ROI. Failing to consider thermal correction can lead to overly optimistic projections with significant financial repercussions. - Reducing EPC Warranty Risk: EPC companies face contractual risks based on PR. Accurate temperature correction helps mitigate damages due to low performance caused by temperature variations. The temperature-corrected PR formula involves key parameters like energy output, nominal power, irradiation levels, and reference irradiation, with the correction factor being crucial in the calculation process. Understanding and applying the formula for Temperature-Corrected PR is not just a technicality but a fundamental aspect impacting the financial viability and operational success of solar power projects. #SolarEnergy #RenewableEnergy #EnergyEfficiency

?We’re sharing a sneak peek movie from our construction work at the 32 MWp site. ??We conducted electroluminescence testing on PV modules on-site, which is important for making sure the solar panels are top quality and will perform as expected. ???? ??Next up, we're preparing to deliver and install the substation. As part of our #EPC agreement with the investor, we'll also be in charge of connecting the installation to the distribution network and making sure it's all seamless. Stay tuned for more updates as we continue to power progress! ???? ??Why do we recommend the electroluminescence (EL) testing of PV modules? This is an effective quality control measure that provides a comprehensive insight into the internal structure and potential defects in solar panels like micro-cracks, broken cells, and other issues that may not be apparent through standard visual inspections. The key advantage of EL testing is its ability to detect early-stage defects, allowing for prompt repairs or replacements before installation. This results in higher performance, a longer lifespan and greater energy yield for the solar modules, which in turn increases the efficiency and reliability of the entire solar power system. #RenewableEnergy #SolarPower #NomadElectric

Renewables such as #PV, #BESS, and #Wind power plants are not merely connected to the?grid to feed in power.?Grid code compliance provides the technical requirements to ensure grid stability, safety, and reliability when connected.

As the renewable energy sector continues to grow, ensuring the stability and reliability of power systems is becoming more critical than ever. One key area often overlooked is subsynchronous studies—analyzing and mitigating subsynchronous resonance (SSR) and control interactions in renewable energy plants. These studies are especially important as renewable plants increasingly connect to series-compensated transmission lines or utilize grid-following and grid-forming inverters. Without proper analysis, SSR can lead to oscillatory instabilities that affect both plant performance and broader grid operations. Key aspects of a detailed subsynchronous study include: Resonance Analysis: Identifying potential risks of torsional and electrical resonance. Control Interaction Evaluation: Assessing the dynamic interaction between power electronics and the grid. Mitigation Strategies: Implementing damping controls, tuning inverter parameters, and grid modifications to ensure stability. By conducting these studies at the design, commissioning, and operational stages, we can proactively enhance grid reliability, minimize downtime, and support the seamless integration of renewable energy into the power system. As we move toward a cleaner energy future, let’s not overlook the finer details that ensure it’s also a stable and secure one. I’d love to hear your thoughts on subsynchronous studies and how they’re being approached in your projects. Let’s connect and collaborate to drive innovation in this space! #RenewableEnergy #GridStability #PowerSystems #EngineeringInnovation #EnergyTransition

As the global energy transition accelerates, the surge in renewable energy demand is creating unprecedented opportunities for the photovoltaic (PV) industry. According to the International Energy Agency (IEA), global PV installations will continue to grow in the coming years, with increasingly diverse applications and a shift toward high-power and high-voltage systems. One effective way for the PV value chain to reduce costs is through system voltage upgrades. Industry calculations indicate that 2000V is an optimal voltage level, balancing operational, safety, and component requirements. Compared to 1500V systems, 2000V systems can improve overall power generation efficiency by approximately 1%. However, higher voltages demand enhanced electrical insulation and withstand voltage capabilities from components and materials. Connectors, which enable the safe and efficient transmission of electricity between components such as modules, inverters, junction boxes, and controllers, are critical for ensuring the long-term safety of high-voltage systems. Among current connector materials like PC, mPPO, and PA66, BASF’s Ultramid? A3XZG5 R04 stands out. It offers a high Inclined Plane Tracking (IPT) index of up to 2000V and a Comparative Tracking Index (CTI) of 600V. This material demonstrates excellent electrical insulation and withstand voltage performance, meeting UL and TUV certification requirements for 2000V systems. Moreover, Ultramid? maintains its insulating properties even after prolonged exposure to heat and humidity, ensuring safe and reliable operation in complex environments. This not only supports customers in reducing overall operational and maintenance costs but also makes Ultramid? an ideal choice for connectors in 2000V high-voltage systems. #EnergyTransition #RenewableEnergy #Photovoltaics #SolarPower #HighVoltageSystems #BASF #Ultramid #SustainableMaterials #SolarInnovation #2000VSystems
